Definitions
- the invention relates to a method and to an arrangement for the local delimitation of faults in distribution networks, in particular electrical distribution networks.
- the electric power generated by large power stations and decentralized energy generators is transported to the consumers over a supply network. To cover larger distances, the electric power is frequently here first routed over high or extra-high voltage networks before it is further distributed over medium-voltage networks. Individual industrial consumers can be connected directly even to the medium-voltage networks. The great majority of consumers however, private households in particular, obtain electric power over a low-voltage network downstream of the medium-voltage network.
- the high or extra-high voltage network and the medium-voltage network have equipment for monitoring the network at their disposal, and are closely observed in a control centre so that faults can be recognized promptly and rectified where appropriate.
- the network monitoring system here allows the position of a fault in the network to be localized accurately, in order either to take measures aimed directly at the site of the fault for rectifying the fault, or to isolate the site of the fault at least temporarily from the rest of the network, so that the fault does not propagate into other regions of the network.
- the operator of a low-voltage distribution network is, rather, frequently reliant on the report of a fault, for example of a power failure, by third parties such as end-customers, and can only then begin the search for the fault.
- the operator is here already able, on the basis of one or a plurality of reports, to delimit a region of his distribution network in which the fault has a high probability of lying. If the operator receives a message that the power has failed at a user, the cause of the fault can namely be presumed initially to be in the conduction path from the point at which the electric power is fed into the low-voltage distribution network and the address of the user. A further localization of the fault is not, however, readily possible. The operator therefore must perform a costly search for the true site of the fault.
- the European patent application EP 2 806 572 A1 proposes an arrangement in which, through communication with and between intelligent electricity meters (“smart meters”) connected to the low-voltage distribution network, which takes place over the lines of the network, it can be established whether measurable signal attenuations or communication failures are occurring. The latter can supply an indication of the location of the fault.
- smart meters intelligent electricity meters
- the invention is based on the object of creating a method and an arrangement for the local delimitation of faults in distribution networks, in which the known disadvantages of the prior art no longer occur or at least only do so to a reduced extent.
- the invention accordingly relates to methods for the local delimitation of faults in an electrical distribution network with a receiver unit comprising a position determination module and with a database comprising position information about devices, connected to the distribution network, which transmit radio signals identifiable by the receiver unit and assignable to the respective device, with the steps of:
- the invention further relates to an arrangement for the local delimitation of faults in an electrical distribution network, comprising a receiver unit with a position determination module, a database comprising position information about devices, connected to the distribution network, which transmit radio signals identifiable by the receiver unit and assignable to the respective device, and a computer, where the computer is designed to determine from the database, with reference to the position determined by the position determination module of the receiver unit, devices located in the neighbourhood of the receiver unit, and to check, with reference to the radio signals received by the receiver unit, which of the devices determined in this way are active and which of the devices determined in this way are deactivated.
- radio signals transmitted by devices are “identifiable and assignable to the respective device” if at least one distinguishable identification feature which is suitable for assigning the radio signal to a single device as a unique source can be derived from a received radio signal.
- radio signals repeatedly transmitted for identification (“Beacons”) by transmitters for digital radio networks e.g. a “Wireless Local Area Network”, WLAN
- transmitters for digital radio networks regularly also have, in addition to an identifier of the network (“Service Set Identifier”, SSID), an identifier that identifies the transmitter or the device (“Media Access Control” address, MAC address), so that on reception of the radio signal one device can be uniquely identified as the transmitter.
- SSID Service Set Identifier
- MAC address Media Access Control
- a device is considered to be “active” if it transmits radio signals which, in principle, can be received by the receiver unit and which are identifiable and assignable to a device.
- a device is then considered to be “deactivated” if, while it is in principle suitable for transmitting corresponding radio signals in order to be counted as an active device in the sense of the invention, it does not however transmit any radio signals at the time when the method according to the invention is carried out. Apparatuses that cannot transmit any radio signals that are, in principle, identifiable and assignable, are not “devices” in the sense of the invention.
- a comparison is made between the radio signals of devices that are indeed active received by the receiver unit and the, in principle, expected radio signals from devices located in the neighbourhood of the position of the receiver unit which are determined from a database in the light of the position of the receiver unit.
- the devices in the neighbourhood of the receiver unit that are deactivated can be determined from this comparison.
- the information regarding active and deactivated devices can be used in order to be able to delimit the location of the fault in the distribution network.
- the invention is based here on the fundamental principle that active devices connected to the distribution network will become deactivated due to the cessation of the power supply in the presence of a fault in the distribution network, e.g. a power failure, or the “tripping” of a circuit breaker.
- the database used in the invention comprises position information about devices connected to the distribution network which are, in principle, capable of transmitting identifiable and assignable radio signals.
- the position information can here comprise particulars of the geographical position, for example in the form of geographical coordinates, and/or position in the network topology.
- Position in the network topology here refers to information from which the line of the distribution network to which a device is connected, or the line node of the distribution network through which the supply of electrical energy to the device is made, emerges unambiguously.
- the database can contain information about the time-dependent activation and deactivation of at least some of the devices connected to the distribution network in order to ensure that a corresponding device, which is only active at certain times, and is determined to be deactivated in the method according to the invention is incorrectly deemed to be an indication of a possible fault in the network, although it was only deactivated in accordance with a predetermined schedule. It is thus possible to check for devices that are only active at certain times whether they are inactive as a result of the respective schedule or whether a determination of the device as deactivated could represent an indication from a fault in the network.
- the database also contains information about whether devices connected to the distribution network have an uninterruptible power supply (UPS).
- UPS uninterruptible power supply
- Such devices with UPS in principle transmit radio signals that are understood by the receiver unit as an indication of an active device, at least for a certain period of time, even in the presence of a fault in the network and, for example, the cessation of the supply of electrical power over the distribution network.
- radio signals that are understood by the receiver unit as an indication of an active device, at least for a certain period of time, even in the presence of a fault in the network and, for example, the cessation of the supply of electrical power over the distribution network.
- corresponding information in the database can be helpful, so that devices with uninterruptible power supplies can be excluded where appropriate from the local delimitation of faults in the distribution network.
- the active devices located in the neighbourhood of the receiver unit are first determined, wherein this determination is made with reference to the radio signals transmitted by these active devices which can be identified by the receiver unit and can be assigned to the respective device.
- the determination can, for example, result in a list of devices located in the neighbourhood of the receiver unit and which are indeed active.
- the position of the receiver unit is then determined by means of the position determination module associated with it.
- the position of the receiver unit can here be determined by methods known from the prior art.
- satellite navigation signals e.g. GPS, Galileo or GLONASS
- a position determination on the basis of radio signals that are identifiable by the receiver unit and assignable to a device is also possible.
- the approximate position of the receiver unit can be derived from this.
- the position of the devices in question can, for example, come from the previously described database.
- information about its position can also be stored in a memory from which the position determination module retrieves this information.
- the memory can here be directly assigned to the receiver unit or can be stored elsewhere in the form of a database, from which the position module can then call up the stored position, for example with the aid of a unique identifier of the receiver unit. It is also possible, in particular in the case of mobile receiver units, to store the most recently determined position in the memory regularly. The position stored in the memory can then be accessed if the requirement arises to determine the position of the receiver unit. This is in particular advantageous when a true position determination is not possible at the time of the requirement, for example because radio signals that can be evaluated are absent.
- the position of the receiver unit can—similarly to the position of the devices—be represented in the form of geographical coordinates and/or as a position in the network topology.
- the way in which the position of the receiver unit is represented here depends in particular on the type of determination of the position of the receiver unit and on the design of the receiver unit as a mobile or stationary unit.
- the position determination module for determining position does not make use of the received radio signals of the active devices, it is also possible for the determination of the position of the receiver module to take place in parallel with or in advance of the determination of the active devices located in the neighbourhood of the receiver unit.
- the devices located in the neighbourhood of the receiver unit are determined from the database on the basis of the determined position of the receiver unit.
- a determination is made through the database of which devices the receiver unit ought, in principle, to receive on the basis of its position, wherein—to the extent available—information about the time-dependent activation and deactivation of the devices can, of course, be taken into account.
- the deactivated devices located in the neighbourhood of the receiver unit can be determined.
- the location of a fault in the distribution network can usually already be delimited through an evaluation of the position information originating from the database of the determined active and deactivated devices:
- the position information of devices in the database is present in the form of geographical position information or of positions in the network topology. With sufficient knowledge of the network topology, including the position of the lines, the position information can, if required, be converted with sufficient precision from one form into the other.
- the database prefferably contains position information for devices not connected to the distribution network which transmit radio signals that are identifiable by the receiver unit and assignable to the respective device.
- position determination of the receiver unit takes place on the basis of received radio signals, a position determination is then also still possible if all the devices that are located in the neighbourhood and connected to the supply network are deactivated, for example as a result of a fault in the network.
- Battery-operated devices such as, for example, wireless window contacts of a heating controller or an alarm installation, radio thermostats etc. are examples of devices not connected to the distribution network.
- the devices connected to the distribution network can preferably comprise the network operator's own devices such as, for example, electricity meters and/or distribution boxes.
- Corresponding devices offer the advantage that they directly have a unique position in the network topology which can simplify the local delimitation of faults.
- the receiver unit can be an (intelligent) electricity meter or a mobile terminal, in particular a so-called smartphone or tablet, which preferably can communicate over a mobile radio network. If the receiver unit is an electricity meter, it preferably has a communication module for transmitting and receiving data. It is to be borne in mind here that—in contrast to the prior art—it is not necessary for all the electricity meters of a distribution network to be electricity meters fitted out in this way.
- the battery charge status and/or the light impinging on a camera of the mobile telephone can also be taken into account in the delimitation of the fault in the distribution network as additional information about the status of the distribution network in the region of the receiver unit. If the mobile telephone establishes that a charging process changes suddenly, for example is interrupted, it can be presumed that the line to which the charging device of the mobile telephone is connected is affected by a fault of the supply network. If, during the night, a significant light incidence is established in the camera, it can be presumed that at least the supply of the electric light via the supply network is not affected by a fault.
- the database it is, in principle, possible for the database to be arranged immediately at the receiver unit. It is, however, preferred for the database to be maintained separately from the receiver unit. This offers the advantage that the database can be used simultaneously by a plurality of receiver units, and it is possible to more easily ensure that the database used by a receiver unit is up-to-date.
- the communication between the receiver unit and the database can here preferably take place over a mobile radio network, at least in the event of failure of other communication routes, for example over the distribution network itself.
- the components of a mobile radio network usually incorporate an emergency power supply, so that the mobile radio network usually continues to be available even when the supply network fails.
- the determination of devices, or of the deactivated devices, located in the neighbourhood of the receiver unit can be carried out by the receiver unit, by the database, or by a computer linked to the database and the receiver unit.
- An appropriate computer can, for example, be provided in the control centre of the network operator.
- the database is self-learning, and information relating to the connection to the distribution networks and/or an uninterruptible power supply of individual devices is preferably updated as required. If, for example, it is established during a failure of a line of the supply network that the radio signals of a device connected thereto only cease after a time delay or not at all, it can be presumed that this device has an uninterruptible power supply. If the radio signal of an entirely unknown device is identified, it can basically be concluded that a new device has been connected to the distribution network.
- the database can be correspondingly extended, wherein the position information can initially be estimated in an automated manner depending on the position of the receiver unit, and made more precise in the course of time, for example in that each time a radio signal is received from this device, a check is made as to whether its position information can basically be correct or not. In the latter case, the position information is systematically modified. It remains, of course, possible, even for a self-learning database, for individual devices to be recorded or for their data records to be updated manually.
- the radio signals that can be identified by the receiver unit and assigned to a device are preferably WLAN, Bluetooth, Zigbee, Z-Wave and/or EnOcean signals.
- FIG. 1 shows a first exemplary embodiment of an arrangement according to the invention with a supply network in the state without fault
- FIGS. 2 a - b show various network states of the arrangement of FIG. 1 .
- An electrical distribution network 1 is illustrated schematically in FIG. 1 , being connected to an upstream network (not illustrated) at the connection point 2 , and distributes the electrical line leading from there over a branched supply network 3 .
- a plurality of devices 4 . 1 to 4 . 11 are connected to the distribution network 1 , each of which, when in the active state, emits a radio signal identifiable by one of the receiver units 9 . 1 to 9 . 3 , which are explained further below, and which can be unambiguously assigned to a device 4 . 1 - 4 . 11 .
- the range of the respective radio signal is suggested by the dotted circles around the respective devices 4 . 1 - 4 . 11 .
- the device 4 . 2 has an uninterruptible power supply 6 , so that even when the distribution network 1 fails, it can still continue to be operated.
- the device 4 . 6 is connected to the distribution network 1 through a timer switch 7 , and is only active between the times of 09:00 and 17:00.
- a further device 8 which, while it also transmits identifiable and assignable radio signals, is however operated with a battery entirely independently of the distribution network 1 .
- receiver units 9 . 1 , 9 . 2 and 9 . 3 are also drawn in FIG. 1 in the region of the distribution network 1 .
- These receiver units 9 . 1 , 9 . 2 and 9 . 3 are mobile telephones or smartphones that are designed to receive the radio signals transmitted by the devices 4 . 1 - 4 . 11 , 8 when in the active state, and which, moreover, have a position determination module (not illustrated) for determining the position of the respective receiver units 9 . 1 , 9 . 2 , 9 . 3 .
- the receiver units 9 . 1 , 9 . 2 and 9 . 3 also have a communication module, so that data relating to the position of the receiver unit 9 . 1 , 9 . 2 , 9 . 3 and the radio signals received by the receiver unit 9 . 1 , 9 . 2 , 9 . 3 via a mobile radio network suggested by a mobile radio mast can be transmitted to a computer 11 .
- the computer 11 furthermore has access to a database 12 .
- Position information on all the devices 4 . 1 - 4 . 11 , 8 is registered in the database 12 , where the information comprises both particulars of the geographical position in the form of geographical coordinates as well as details on the position in the network topology—i.e. to which line 3 in the supply network 1 the respective device 4 . 1 - 4 . 11 , 8 is connected.
- a receiver unit 9 . 1 , 9 . 2 , 9 . 3 regularly, on establishing a sudden cessation of one or more radio signals, or in response to an explicit command of a user, transmits the information over the mobile radio network 10 to the computer 11 relating to the received radio signals, with reference to which the devices 4 . 1 - 4 . 11 , 8 are identifiable, and the individual radio signals are uniquely assignable to an individual device 4 . 1 - 4 . 11 , 8 .
- the receiver units 9 . 1 , 9 . 2 , 9 . 3 also transmit the position of the receiver unit 9 . 1 , 9 . 2 , 9 . 3 determined by their respective position determination module.
- the position determination is performed by means of GPS signals, while the precision of the position determination can be increased in the known manner through the evaluation of WLAN signals which can, for example, involve radio signals transmitted by the devices 4 . 1 - 4 . 11 , 8 .
- the position of the receiver unit 9 . 1 , 9 . 2 , 9 . 3 is determined in geographical coordinates.
- the computer 11 can determine, with reference to the database 12 , which devices 4 . 1 - 4 . 11 , 8 are essentially located in the neighbourhood of the respective receiver unit 9 . 1 , 9 . 2 , 9 . 3 . It is, in other words, possible to determine the devices 4 . 1 - 4 . 11 , 8 from which a receiver unit 9 . 1 , 9 . 2 , 9 . 3 should in principle receive radio signals, bearing in mind the respective range 5 , provided the devices 4 . 1 - 4 . 11 , 8 are active. In the exemplary embodiment illustrated these are, for the receiver unit 9 .
- the devices 4 . 3 , 4 . 4 and 4 . 7 for example the devices 4 . 3 , 4 . 4 and 4 . 7 , for the receiver unit 9 . 2 the devices 4 . 1 , 4 . 2 , 4 . 5 , 4 . 6 and 8 , and for the receiver unit 9 . 3 the devices 4 . 6 , 4 . 9 and 4 . 10 .
- all the devices 4 . 1 - 4 . 11 , 8 are active, and thus transmit radio signals which—provided they are located within the respective range 5 —can be received by the receiver units 9 . 1 , 9 . 2 , 9 . 3 .
- the information transmitted by the receiver units 9 . 1 , 9 . 2 , 9 . 3 regarding the received radio signals, which can be assigned by the computer 11 unambiguously to the respective devices 4 . 1 - 4 . 11 , 8 that are transmitting the radio signals with the aid of the database 12 in this case fully matches the respective devices previously determined as being in the neighbourhood of the receiver units 9 . 1 , 9 . 2 , 9 . 3 .
- a corresponding comparison carried out by the computer 11 suggests that there is no fault in the supply network 1 , since all the checkable devices 4 . 1 - 4 . 7 , 4 . 9 , 4 . 10 connected to the network are clearly active. If a radio signal could not be received from one of the said devices, it is basically possible to assume that the device concerned is deactivated, which in turn can represent an indication of a fault in the network.
- FIG. 2 a A first case of a fault in the supply network 1 according to FIG. 1 is illustrated in FIG. 2 a .
- the actual fault is marked as X, and fully interrupts the supply of power to the devices located behind the fault, as seen from the connecting point 2 .
- the devices 4 . 1 , 4 . 2 , 4 . 3 and 4 . 4 are thus affected by the fault.
- the active and deactivated devices 4 . 1 - 4 . 11 , 8 can be determined for each receiver unit 9 . 1 , 9 . 2 , 9 . 3 .
- the receiver unit 9 . 1 It can thus be determined for the receiver unit 9 . 1 that the devices 4 . 3 , 4 . 4 , whose radio signals ought in principle to be received, are clearly deactivated, whereas the device 4 . 7 is still transmitting radio signals, and device 4 . 7 is thus active. With just this information it is possible to derive from the network topology—in an automated manner by the computer 11 where appropriate—that the fault presumably lies between the line branch 3 . 1 and the device 4 . 4 .
- the results of the other receiver units 9 . 2 and 9 . 3 can confirm this presumption. Since the receiver unit 9 . 3 continues to receive the radio signals of the devices 4 . 9 and 4 . 10 , it can be presumed that the line is free from faults between the connecting point 2 and the device 4 . 9 . The fact that no radio signals can be received from the device 4 . 6 does not, on the other hand, provide an indication of a fault in its supply line, since this device 4 . 6 in the state illustrated in FIG. 2 a is switched off by the timer switch 7 , and has thus been intentionally deactivated. Since appropriate information about the deactivation of the device 4 . 6 at certain times is stored in the database 12 , the computer 11 can identify the absence of the radio signals of the device 4 . 6 as being in order, and not as a state indicating a network fault.
- the receiver unit 9 . 2 can also no longer receive radio signals of the device 4 . 6 , which however again, with reference to the information from the database 12 , is not understood as a fault of the supply network 1 . Since the receiver unit 9 . 2 continues not to receive any signals from the device 4 . 1 , but only from the devices 4 . 2 , 4 . 5 and 8 , a fault in line 3 , which leads from the line branch 3 . 1 to the device 4 . 1 , is also indicated. Since it is known from the database 12 that the device 4 . 2 has an uninterruptible power supply, the possibility that the radio signals of this device 4 . 2 are incorrectly seen as an indication of a functioning power supply to the device 4 . 2 by the supply network 1 is avoided.
- FIG. 2 b An alternative case of a fault in the supply network 1 according to FIG. 1 is illustrated in FIG. 2 b .
- the fault marked as X occurs in the line between the devices 4 . 3 and 4 . 4 .
- the receiver unit 9 . 1 also still receives the radio signals of the device 4 . 4 in the fault according to FIG. 2 b .
- the computer 11 Through the evaluation of the computer 11 , as described in association with FIGS. 1 and 2 b , it is thus possible to directly establish that the fault presumably lies in the line between device 4 . 3 and 4 . 4 .
- the radio signals transmitted by the devices 4 . 1 - 4 . 11 , 8 are WLAN signals, in particular WLAN beacons, which can be received and evaluated without, for example, a receiver unit 9 . 1 , 9 . 2 , 9 . 3 having to be connected to the corresponding WLAN.
